-LRB- CNN -RRB- -- `` Gigantic , alien-looking buildings '' that bring to mind melted guitars , mushroom-like parasols and UFOs .

That 's how some of the world 's finest examples of `` blob buildings '' have been described , by the company that wants to celebrate them .

Building data company Emporis of Hamburg , Germany , usually gives kudos to more traditional architectural triumphs , such as these new skyscrapers completed last year .

But this time `` we felt that it 's time to highlight this interesting and visually appealing topic , '' says Sarah Krenz , in the Emporis public relations office .

What makes a building a blob ?

`` Unconventional , right-angle-free geometric shapes , '' according to the report . It 's also known as `` liquid architecture . ''

Emporis cites the Experience Music Project in Seattle , locally known as `` The Blob , '' as a prime example .

Others include the Golden Terraces in Warsaw , `` whose wavy roof , created from 4,700 separate glass elements , rests like a frozen liquid over the atrium of this multi-story shopping center . ''

As well as standing out from other buildings in their vicinity , blob buildings often conjure imaginative responses from the public , not always complimentary .

While the Selfridges Building , a shopping center in Birmingham , England , is known as the Beehive due to its honeycomb-like façade , the London City Hall was once described as a `` glass testicle . ''

This list anticipates the opening next year of another `` blob '' -- the exhibition building Fondation Louis Vuitton pour la Création in Paris , designed by Frank O. Gehry .

What do you think ? Are blob buildings creative and inspiring or ugly and over the top ? Comment below .
